Definitions
- the invention relates to a device, a system and a method for producing and handling bundles of staple goods such as logs, such as those used in the processing of firewood.
- Such devices are the subject of the publications CH120123 . EP 0 897 867 A1 . FR 2822135 A1 and US 4,057,262 ,
- This instability is due to the fact that in the manufacture of bundles of staple material with irregular cross-section and circular waist circumference, the circumferential force of the tension belt leads to the formation of a positive connection in the region of the waistband circumference. As a result, the tension belt can not compress the central region of the federal government. For example, this leads to the production of bundles of logs to the fact that fall out of the central collar area in handling the bundles logs.
- a system for bundling, cutting, stocking, volume determination and transport of firewood in which a bundle of firewood created for compact processing is prepared for firing desired final length for a handy onward transport to the firing point.
- a device which consists of at least two individually movable units, which are coupled to each other in the federal axis direction, that between the units the AblCodeitese are feasible.
- the firewood collar is inserted into the system, for which each unit has an upwardly open, semi-circular receptacle that is compatible with the geometric shape of the male collar.
- the inserted firewood bundle is cut between the units by a single cutting cut.
- at least one unit of the system can be individually and independently of the other units, loaded with the cut firewood, proceed to the Ver85ungsstelle.
- This system is thus primarily suitable for the production of logs in the desired kiln length and for the firing in the rhythm of Feuerungs loces.
- For the preparation of a stock also a variety of units of the system is needed, which is relatively space and cost intensive.
- this system For the production of bundles with the content of a room meter and a weight of about 600 kg, this system is also not suitable because u. a. too heavy for the units of the system. Nor can the standard amount of logs of one meter of bulk produced economically.
- a device for the manufacture of firewood pieces and / or firewood coils known, which has a lateral connection plate and two aligned with this and at an axial distance from each other and upwardly open semicircular bracket for receiving the firing.
- the front bracket is rigidly mounted on a frame member, while the rear bracket and / or the stop plate are arranged axially displaceable.
- This device primarily serves the sawing off of the inserted firewood in the desired length, but is in principle also suitable for bundling inlaid logs. Although no statement is made about the way in which bundles are bundled, only the usual lashing over straps or strapping can take place here. This also remains in the interior of the interior only an insufficient holding voltage, so that the inner logs can fall out during transport.
- the object of the invention is therefore to provide a device, a system and a method of the type described above for producing and handling / transporting staple goods which are simple and safe and by which during manufacture, but also when handling bundles of bundles, the central area of the bundle is compressed and remains so that no logs fall out of it.
- the device according to the invention of two on a base plate, preferably a Euro pallet, oppositely mounted support brackets.
- a first support bracket is arranged so as to be displaceable on the base plate, while a second support bracket is displaceable parallel to the first support bracket on the base plate from a first position, the basic position for loading, in a second position spaced from the first support bracket or other positions.
- the insertion longitudinal axis of the device which is also the longitudinal axis of the federal government to be created, extends between the two support blocks in their first position.
- each support bracket consists of two in the direction of the insertion longitudinal axis of the device parallel to each other and mutually firmly connected side walls.
- the second support bracket is provided with an axially oriented belt deflection, which projects radially into the interior of the recess.
- a tensioning lock via a turnbuckle and tensionable strap is provided, which is so feasible around the federal government, that it is deflected engaging over the belt deflection in the Bundinnere.
- the circular segment-shaped recess is a total of over 180 °, preferably about 270 ° (135 ° per support bracket).
- the recess is pulled in cross section far above a semicircle, whereby the circular shape bond of the Federal Government is much higher.
- the logs can be safely and accurately inserted to the upper vertex of the covenant, without the risk that an uneven shape of the collar is obtained and / or slip off the slabs laterally when layering.
- the belt deflection consists of an axially oriented rod or strip, which is supported at its two ends in horizontal-radially projecting from the support walls of the support bracket holding arms.
- the clamping force of the belt acts radially-horizontally on the belt deflection, whereby the bearing force on the outer lower end of the support bracket and thus the frictional force acting between the support bracket and base plate is increased. It adjusts an equilibrium of forces between the belt force, the bearing force acting on the support block federal force and the frictional forces between the support bracket and the base plate.
- a standard Euro pallet is used as the base plate, for. Trademarks EPAL, LPR, WORLD, CHEP.
- Europaletten preferably have dimensions of 800 mm x 1200 mm and are inter alia, with five longitudinal cover boards and attached below three cross boards, which form between them in the longitudinal direction one behind the other two transverse rows of four with gaps.

Description
Die Erfindung bezieht sich auf eine Vorrichtung, ein System und ein Verfahren zum Herstellen und Handhaben von Bunden aus Stapelgut wie Holzscheiten, wie sie bei der Aufbereitung von Brennholz Verwendung finden. Solche Vorrichtungen sind Gegenstand der Druckschriften
Die Herstellung und Handhabung von Bunden aus Stapelgut mit unterschiedlichem Querschnitt und unterschiedlicher Länge hat insbesondere bei der Aufbereitung von Brennholz ein spezielles Anwendungsgebiet. Deshalb wird die Funktionsweise der vorliegenden Vorrichtung am Beispiel der Holzaufarbeitung im Umfeld kleiner Betriebe erläutert.The production and handling of bundles of staple goods with different cross sections and different lengths has a special field of application, especially in the processing of firewood. Therefore, the operation of the present device will be explained using the example of woodworking in the environment of small businesses.
Wesentliche Schritte der Brennholzaufarbeitung sind bekanntlich das Metern und Spalten des Stammholzes, der Transport zum Lagern für die Trocknung, das Sägen und die Lagerung der Holzscheite in der für die Verbrennung gewünschten Länge. Alternativ zum Stapeln von Holzscheitbänken und der Lagerung in Gitterboxen werden auch Holzbunde eingesetzt. Holzbunde können zum Trocknen auf Lücke gesetzt zu Bänken mit mehreren Etagen gestapelt werden. Dadurch entfällt das arbeitsintensive Handhaben einzelner Holzscheite. Das dem Bedarf entsprechende Absägen der ofenfertigen Holzscheite vom Bund ist jedoch wegen der Instabilität der Bunde während des Transportes und des Sägens oft nicht möglich. Diese Instabilität ist dadurch begründet, daß beim Herstellen von Bunden aus Stapelgut mit unregelmäßigem Querschnitt und kreisförmigem Bundumfang die Umfangskraft des Spanngurtes zur Bildung eines Formschlusses im Bereich des Bundumfanges führt. Dadurch bedingt kann der Spanngurt den zentralen Bereich des Bundes nicht verdichten. Beispielsweise führt dies bei der Herstellung von Bunden aus Holzscheiten dazu, dass aus dem zentralen Bundbereich bei der Handhabung der Bunde Holzscheite herausfallen.Essential steps in firewood processing are known to be the metering and splitting of the logs, the transport for storage for drying, sawing and storage of the logs in the desired length for combustion. As an alternative to stacking wooden logs and storing in lattice boxes, wooden bundles are also used. Timber coils can be stacked to dry on gap stacked on benches with multiple floors. This eliminates the labor-intensive handling of individual logs. However, the sawing off of the ready-to-use wood logs from the Federal Government is often not possible because of the instability of the bundles during transport and sawing. This instability is due to the fact that in the manufacture of bundles of staple material with irregular cross-section and circular waist circumference, the circumferential force of the tension belt leads to the formation of a positive connection in the region of the waistband circumference. As a result, the tension belt can not compress the central region of the federal government. For example, this leads to the production of bundles of logs to the fact that fall out of the central collar area in handling the bundles logs.

Zwar wird ausgeführt, daß dieses bekannte System ebenso zur Erzeugung von Brennholzbunden geeignet ist. Dafür wird zusätzlich, um einen Zusammenhalt des Bundes zu gewährleisten, z. B. ein handelsübliches Umreifungsgerät benötigt. Abgesehen davon, daß die nur halbkreisförmigen Bundaufnahmen der Einheiten hierfür nicht optimal geeignet sind, sind die erzeugten Bunde nicht durchgehend gleichförmig gespannt, so daß bei Entnahme der Bunde deren inneren Holzscheite sich lösen und das gesamte Bündel auseinanderfällt.Although it is stated that this known system is also suitable for the production of firewood coils. In addition, in order to ensure cohesion of the federation, z. B. a commercial strapping machine needed. Apart from the fact that the only semicircular fret recordings of the units are not optimally suited for this purpose, the coils are not continuously uniformly stretched, so that upon removal of the bundles their inner logs loose and the entire bundle falls apart.
Dieses System ist somit erstrangig für die Herstellung von Holzscheiten in der gewünschten Ofenlänge und für die Verfeuerung im Rhythmus des Feuerungsbedarfes geeignet. Für die Herstellung eines Vorrates wird zudem eine Vielzahl an Einheiten des Systems benötigt, was relativ platz- und kostenintensiv ist. Für die Herstellung von Bunden mit dem Inhalt eines Raummeters und eines Gewichtes von ca. 600 Kg ist dieses System ebenfalls nicht geeignet, da u. a. zu schwer für die Einheiten des Systems. Auch lässt sich die marktübliche Scheitholzmenge von einem Schüttmeter nicht wirtschaftlich herstellen.This system is thus primarily suitable for the production of logs in the desired kiln length and for the firing in the rhythm of Feuerungsbedarfes. For the preparation of a stock also a variety of units of the system is needed, which is relatively space and cost intensive. For the production of bundles with the content of a room meter and a weight of about 600 kg, this system is also not suitable because u. a. too heavy for the units of the system. Nor can the standard amount of logs of one meter of bulk produced economically.
Zudem lockert sich erfahrungsgemäß infolge der Trocknung die Umschließung der Bunde, so dass sie ihre Form der Geometrie im Stapel anpassen. Solche Bunde verlieren ihren kreisförmigen Querschnitt und lassen sich daher nur unter kontrolliertem Entspannen eines Gurtes in eine kreisförmige Aufnahme- Halbschale einlegen. Um die Kreisform der Bunde wieder herzustellen, müssen die Holzscheite arbeitsaufwändig im oberen Teil des Querschnittes geordnet und neu verspannt werden. Hierfür sind im bekannten System jeweils an der Oberseite der Einheiten Vorspannvorrichtungen vorsehbar.In addition, experience has shown that, as a result of the drying process, the enclosures of the bundles loosen, so that they adapt their shape to the geometry in the stack. Such bundles lose their circular cross section and can therefore only under controlled Relax a belt in a circular receiving half-shell insert. To restore the circular shape of the bundles, the logs must be laboriously arranged in the upper part of the cross section and re-tensioned. For this purpose, prestressing devices can be provided in each case in the known system at the top of the units.

Ähnliche Systeme oder Vorrichtungen, jedoch mit mehreren Auflagebügeln, sind am Markt in unterschiedlichen Varianten bekannt, wie insbesondere aus dem Internet entnehmbar ist. Siehe hierzu das STERFIX ® Holzbündelgerät ST-FP 03, der Firma Huber Landtechnik, 77770 Durbach, www.huber-landtechnik.de, oder das Brennholzbündeln mit dem KNÖTI.wmv, unter www.zurrbind.de. Die Bündelauflagen oder -Bügel sind auch bei diesen Vorrichtungen jeweils halbkreisförmig (180°) nach oben offen, wodurch beim Einlegen die Scheite seitlich herabfallen können. Auch werden bei all diesen Vorrichtungen die eingelegten oder erzeugten Bunde in der Vorrichtung in die gewünschte Scheitlänge gesägt.Similar systems or devices, but with several support brackets, are known on the market in different variants, as can be seen in particular from the Internet. See the STERFIX ® wood bundle unit ST-FP 03, the company Huber Landtechnik, 77770 Durbach, www.huber-landtechnik.de, or the firewood bundling with the KNÖTI.wmv, at www.zurrbind.de. The bundle supports or straps are also in these devices each semicircular (180 °) open at the top, so that when inserting the logs can fall laterally. Also, in all these devices, the inserted or produced coils in the device are sawn into the desired log length.
Aufgabe der Erfindung ist es somit, eine Vorrichtung, ein System sowie ein Verfahren vorbeschriebener Art zum Herstellen und Handhaben/Transportieren von Stapelgut anzugeben, die einfach und sicher sind und durch welche beim Herstellen, aber auch beim Handhaben von Bunden aus Stapelgut auch der zentrale Bereich des Bundes so verdichtet wird und bleibt, dass aus diesem keine Holzscheite herausfallen. The object of the invention is therefore to provide a device, a system and a method of the type described above for producing and handling / transporting staple goods which are simple and safe and by which during manufacture, but also when handling bundles of bundles, the central area of the bundle is compressed and remains so that no logs fall out of it.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den entsprechend rückbezogenen Unteransprüchen gekennzeichnet.This object is achieved by a device having the features of
Demgemäß besteht die erfindungsgemäße Vorrichtung aus zwei auf einer Grundplatte, vorzugsweise einer Europalette, gegenüberliegend aufgesetzten Stützböcken. Dabei ist ein erster Stützbock verschiebefest auf der Grundplatte angeordnet, während ein zweiter Stützbock in Bezug zum ersten Stützbock auf der Grundplatte parallel verschiebbar ist und zwar aus einer ersten Stellung, der Grundstellung zum Beladen, in eine vom ersten Stützbock beabstandete zweiten Stellung oder weitere Stellungen. Zudem verläuft die Einlege-Längsachse der Vorrichtung, die gleichzeitig die Längsachse des zu erstellenden Bundes ist, zwischen den zwei Stützböcken in deren erster Stellung. Die Stützböcke besitzen dabei in der ersten (Arbeits-) Stellung oberseitig gemeinsam eine kreissegmentförmige Ausnehmung in Form des zu formenden Bundes, deren unterer Scheitelpunkt die Oberfläche der Palette berührt, wobei die Erstreckung einer jeweiligen kreissegmentförmigen Ausnehmung insgesamt mehr als 180° beträgt. Zudem besteht ein jeder Stützbock aus zwei in Richtung der Einlege-Längsachse der Vorrichtung zueinander parallel beabstandeten und miteinander fest verbundenen Seitenwänden. Dabei ist der zweite Stützbock mit einer axial ausgerichteten Gurtumlenkung versehen, die radial in das Innere der Ausnehmung hineinragt. Schließlich ist ein über ein Spannschloß schließ- und spannbarer Spanngurt vorgesehen, der um das Bund so führbar ist, dass er über die Gurtumlenkung in das Bundinnere eingreifend umgelenkt ist.
Hierdurch ist eine in Aufbau und Handhabung einfache und gleichzeitig sichere Vorrichtung vorhanden, durch welche auch der zentrale Bereich der hergestellten Bunde so verdichtet ist, dass aus diesem zentralen Bundbereich bei deren Handhabung keine Holzscheite herausfallen. Die beim Spannen des Spanngurtes wirkende Kraft drückt die Gurtumlenkung radial aus dem Bundquerschnitt, wobei die auf den Umfang des Bundes wirkende Spannkraft des Spanngurtes mittels der Gurtumlenkung in die Mitte des Querschnitts des Bundes geleitet wird. Gleichzeitig wird dadurch der zweite Stützbockverschoben und dadurch der Stützbock vom Bund getrennt.Accordingly, the device according to the invention of two on a base plate, preferably a Euro pallet, oppositely mounted support brackets. In this case, a first support bracket is arranged so as to be displaceable on the base plate, while a second support bracket is displaceable parallel to the first support bracket on the base plate from a first position, the basic position for loading, in a second position spaced from the first support bracket or other positions. In addition, the insertion longitudinal axis of the device, which is also the longitudinal axis of the federal government to be created, extends between the two support blocks in their first position. The support blocks have in the first (working) position at the top together a circular segment-shaped recess in the form of the federal government whose lower vertex touches the surface of the pallet, wherein the extension of a respective circular segment-shaped recess is more than 180 °. In addition, each support bracket consists of two in the direction of the insertion longitudinal axis of the device parallel to each other and mutually firmly connected side walls. In this case, the second support bracket is provided with an axially oriented belt deflection, which projects radially into the interior of the recess. Finally, a tensioning lock via a turnbuckle and tensionable strap is provided, which is so feasible around the federal government, that it is deflected engaging over the belt deflection in the Bundinnere.
As a result, a simple and at the same time safe in construction and handling device is present, through which the central region of the coils produced is compressed so that fall out of this central collar area when handling no logs. The force acting during tensioning of the tension belt presses the belt deflection radially out of the collar cross section, wherein the on the circumference the federally acting clamping force of the tension belt is guided by means of the belt deflection in the middle of the cross section of the federal government. At the same time, the second support bracket is displaced thereby separating the support bracket from the collar.
Von Vorteil ist, wenn die kreissegmentförmige-Ausnehmung insgesamt über 180°, vorzugsweise ca. 270° beträgt (je 135° je Stützbock). Dadurch ist die Ausnehmung im Querschnitt weit über einen Halbkreis hoch gezogen, wodurch die kreisförmige Formgebund des Bundes wesentlich höher vorgegeben ist. Dadurch können die Holzscheite bis zum oberen Scheitelpunkt des Bundes sicher und formgenau eingelegt werden, ohne daß die Gefahr besteht, daß eine ungleichmäßige Form des Bundes erhalten wird und/oder die Scheite beim Einschichten seitlich abrutschen.It is advantageous if the circular segment-shaped recess is a total of over 180 °, preferably about 270 ° (135 ° per support bracket). As a result, the recess is pulled in cross section far above a semicircle, whereby the circular shape bond of the Federal Government is much higher. As a result, the logs can be safely and accurately inserted to the upper vertex of the covenant, without the risk that an uneven shape of the collar is obtained and / or slip off the slabs laterally when layering.
Vorteilhaft ist auch, wenn die Gurtumlenkung aus einer axial ausgerichteten Stange oder Leiste besteht, die an ihren beiden Enden in horizontal-radial von den Stützwänden des Stützbockes abragenden Haltearmen abgestützt ist. Abgesehen davon, daß diese Ausführung sehr einfach gestaltet ist, wirkt die Spannkraft des Gurtes radial-horizontal auf die Gurtumlenkung, wodurch die Auflagekraft am äußeren unteren Ende des Stützbockes und damit die zwischen Stützbock und Grundplatte wirkende Reibungskraft erhöht wird. Es stellt sich ein Kräftegleichgewicht zwischen der Gurtkraft, der auf den Stützbock wirkenden Auflagekraft des Bundes und den Reibungskräften zwischen dem Stützbock und der Grundplatte ein.It is also advantageous if the belt deflection consists of an axially oriented rod or strip, which is supported at its two ends in horizontal-radially projecting from the support walls of the support bracket holding arms. Apart from the fact that this design is very simple, the clamping force of the belt acts radially-horizontally on the belt deflection, whereby the bearing force on the outer lower end of the support bracket and thus the frictional force acting between the support bracket and base plate is increased. It adjusts an equilibrium of forces between the belt force, the bearing force acting on the support block federal force and the frictional forces between the support bracket and the base plate.
Von besonderem Vorteil ist, wenn als Grundplatte eine marktübliche Europalette verwendet wird, z. B. der Marken EPAL, LPR, WORLD, CHEP. Solcherart Europaletten haben vorzugsweise Maße von 800 mm x 1200 mm und sind u. a. mit fünf Längs-Deckbrettern und darunter befestigten drei Querbrettern, die zwischen ihnen in Längsrichtung hintereinander zwei Quer-Viererreihen mit Zwischenräumen bilden. Die beiden Stützböcke sind über die Unterseiten ihrer Seitenwände in die jeweils beiden äußeren Zwischenräume einer Querreihe eingreifend auf der Europalette angeordnet. Hierdurch ist ein sehr einfacher modularer Aufbau vorhanden, wobei mit der Europalette ein allgemein sehr kostengünstiges Zukauf-Bauteil zur Verfügung steht.It is particularly advantageous if a standard Euro pallet is used as the base plate, for. Trademarks EPAL, LPR, WORLD, CHEP. Such Europaletten preferably have dimensions of 800 mm x 1200 mm and are inter alia, with five longitudinal cover boards and attached below three cross boards, which form between them in the longitudinal direction one behind the other two transverse rows of four with gaps. The two trestles are arranged on the undersides of their side walls engaging in the respective two outer spaces of a transverse row on the Euro pallet. As a result, a very simple modular design is available, with the Euro pallet is a generally very inexpensive purchase component available.
Dadurch daß die beiden Seitenwände der Stützböcke unterseitig jeweils eine innere Stufung besitzen, ist in vorteilhafter Weise jeweils eine innere Abstützschulter aus gebildet, über welche die Seitenwände und damit der gesamte Stützbock sich am mittleren/inneren Querbrett der Palette abstützen. Zudem besitzen die beiden Seitenwände der Stützböcke unterseitig außen jeweils auch eine äußere Stufung, wobei diejenige des unverschiebbaren Stützbockes so ausgelegt ist, daß zwischen der inneren und der äußeren Stufung ein Längszapfen gebildet ist, der in den jeweiligen äußeren Zwischenraum der Palette eingreift und sich innen an den Querbrettern abstützt. Die äußere Stufung der Seitenwände des verschiebbaren Stützbockes ist jedoch längenmäßig so ausgelegt, daß ein Verschieben des Stützbockes mindestens um die Eindringtiefe der Gurtumlenkung möglich ist, bildet also einen wesentlich kürzeren Längszapfen. Hierdurch können die beiden Stützböcke, schnell, einfach und positionssicher auf die Palette auf- oder eingesetzt werden, wodurch die Vorrichtung lediglich mit ein paar Handgriffen in Arbeits- oder Beladeposition bringbar ist, ohne weitere Befestigungsvorkehrungen.Characterized in that the two side walls of the support brackets each have an inner gradation on the underside, an inner support shoulder is formed in an advantageous manner, via which the side walls and thus the entire support bracket are supported on the middle / inner cross-section of the pallet. In addition, the two side walls of the support brackets have on the underside each outside also an outer gradation, wherein that of the non-displaceable support bracket is designed so that between the inner and the outer gradation, a longitudinal pin is formed, which engages in the respective outer space of the pallet and inside supported the cross boards. However, the outer gradation of the side walls of the sliding support bracket is designed in terms of length so that a displacement of the support bracket is at least possible by the penetration depth of the belt deflection, thus forming a much shorter longitudinal pin. As a result, the two trestles, fast, easy and secure position on the pallet or be used, whereby the device can be brought only in a few steps in the working or loading position, without further Befestigungsvorkehrungen.
Eine einfache und leichte Konstruktion wird auch dadurch erreicht, daß die feste Verbindung der beiden Seitenwände der Stützböcke jeweils aus mehreren axialen Verbindungsstegen besteht, wobei den unteren Wandflächen jeweils zwei Stege zugeordnet sind, in Querabstand zueinander, jedoch unterschiedlicher Höhe, die zudem weitere Funktionen ausüben, insbesondere beim verschiebbaren Stützbock. So liegt in der ersten Stellung, also in der Belade-Stellung, am verschiebbaren Stützbock der äußere, hintere Steg auf den Deckbrettern der Palette mittig zum Querbrett so auf oder ist so nahe zu diesen angeordnet, daß die Seitenwände in diesem Bereich nicht mit ihrer Unterseite auf dem Querbrett der Palette sich abstützend aufliegen, sondern über den Steg, wodurch eine geringere Auflage- und Reibfläche vorhanden ist.
Zudem ist ein Verriegelungshebel vorgesehen, der vom inneren Steg unverschieblich, jedoch kippbar durchsetzt wird und der unterseitig eine äußere hakenförmige Stufung besitzt. Diese steht in blockierend eingerückter Stellung vorzugsweise im Zwischenraum an der Innenseite des äußeren Querbrettes der Europalette an. Dadurch ist ein Verschieben des Stützbockes während der Bündelung quer nach außen blockiert. Erst durch anhebendes Kippen des Verriegelungshebels wird der Stützbock in Verschieberichtung nach außen entriegelt und kann unter Gurtspannung an der Gurtumlenkung entsprechend verschoben werden.A simple and lightweight construction is also achieved in that the fixed connection of the two side walls of the support brackets each consists of a plurality of axial connecting webs, wherein the lower wall surfaces are each associated with two webs, in transverse distance from each other, but different height, which also perform other functions, especially when sliding support bracket. Thus, in the first position, ie in the loading position, on the sliding support frame of the outer, rear web on the cover boards of the pallet centered on the transverse board so or is so close to this arranged that the side walls in this area not with its underside rest on the transverse board of the pallet supporting, but over the web, whereby a smaller support and friction surface is present.
In addition, a locking lever is provided, which is penetrated by the inner web immovable, but tiltable and the underside has an outer hook-shaped gradation. This is in blocking engaged position preferably in the space on the inside of the outer cross-board of the Euro pallet. As a result, a displacement of the support block is blocked during the bundling transversely outward. Only by lifting the tilting lever tilting the support block is unlocked in the direction of displacement to the outside and can be moved under belt tension on the belt deflection accordingly.
Dabei kann der Verriegelungshebel vorzugsweise aus zwei zueinander quer beabstandeten und fest miteinander verbunden parallelen Wänden bestehen, die jeweils in die beiden inneren Zwischenräume der Palette eingreifen.In this case, the locking lever may preferably consist of two mutually transversely spaced and fixedly connected to each other parallel walls, which engage respectively in the two inner spaces of the pallet.
Schließlich ist zudem am inneren Steg mittig auch ein Stützkeil über ein Langloch in Verschieberichtung des Stützbockes bewegbar angeordnet, gleichzeitig sich unterseitig vorzugsweise auf dem mittigen Deckbrett der Palette abstützend, wobei der Verschiebeweg des Steges im Langloch des Stützkeils geringer als die Eindringtiefe der Gurtumlenkung ist. Wenn der Stützbock nämlich durch die auf die Gurtumlenkung wirkende Gurtkraft aus seinem Formschluß mit dem Bund ausgerückt ist, stößt der durch den Keil geführte innere Steg auf der gegenüberliegenden Seite des entsprechenden Langloches gegen den Keil und rückt ihn im weiteren Verlauf des Spannvorganges aus dem Formschluß mit dem Bund aus. Somit dient der Keil zur Sicherung des auf der Palette aufliegenden fertigen Bundes gegen Nachrollen beim Ausrücken des Stützbockes.Finally, a support wedge is also arranged on the inner web centrally movable over a slot in the direction of the support bracket, at the same time supporting the underside preferably on the central deck board of the pallet, wherein the displacement of the web in the slot of the support wedge is less than the penetration depth of the belt deflection. Namely, when the support block is disengaged from its positive engagement with the collar by the belt force acting on the belt deflection, the inner web guided by the wedge hits against the wedge on the opposite side of the corresponding elongated hole and moves it out of the positive engagement in the course of the tensioning operation the federal government. Thus, the wedge is used to secure the resting on the pallet finished federal against rolling during disengagement of the support bracket.
Der äußere Steg des verschiebbaren Stützbockes trägt zudem einen Fußhebel, der so über eine in diesem vorgesehene (Trapez-) Langloch-Öffnung durch den Steg durchsetzt ist, daß er leicht kippbar ist. Der Fußhebel besteht dabei aus zwei parallelen Fußhebelwänden, die über eine äußere Querstrebe verbunden sind. Dabei liegen die Fußhebelwände unterseitig in den inneren Zwischenräumen der Palette auf dem Querbrett verschieblich auf und üben auf den Steg in leicht angehoben verkippter Stellung eine Gegenkraft aus, die die Reibung zwischen Steg und Deckbrett verringert. Dadurch wird ein reibungsarmes, portionsweises Verschieben des Stützbockes während dem Spannvorgang des Gurtes ermöglicht.The outer web of the movable support bracket also carries a foot lever, which is so interspersed through a provided in this (trapezoidal) slot opening through the web that it is easily tilted. The foot lever consists of two parallel Fußhebelwänden, which are connected via an outer cross member. In this case, the Fußhebelwände are slidably on the underside of the inner spaces of the pallet on the transverse board and exert on the bridge in slightly raised tilted position of a counterforce, which reduces the friction between the bridge and deck board. This allows a low-friction, portion-wise displacement of the support bracket during the tensioning operation of the belt.
Das Verschieben kann auch noch leichter und reibungsärmer realisiert werden, wenn die beiden Verbindungsstege oder zumindest der äußere Steg und der Fußhebel aus Metall oder anderem Material mit niedrigem Reibungskoeffizienten gefertigt sind.The displacement can also be realized more easily and with less friction if the two connecting webs or at least the outer web and the pedal are made of metal or other material with a low coefficient of friction.
Um ein zügiges Arbeiten mit der Vorrichtung zu sichern, ist von Vorteil, wenn der Spanngurt in der ersten Stellung, vor dem Einlegen der Holzscheite, in den Zwischenraum zwischen den Seitenwänden beider Stützböcke so eingelegt ist, daß er mittig auf der Palette aufliegt und jeweils über die oberen Verbindungsstege der Stützböcke gelegt ist und gleichzeitig quer über die Gurtumlenkung verläuft. Dabei ist er über ein Spannschloß schließ- und spannbar. Das eine Gurtende ist mit dem Spannschloß selbsthemmend verbunden. Selbstverständlich können auch zwei Spanngurte eingelegt werden, die dann vorzugsweise jeweils nahe den Seitenwänden einzulegen sind.To ensure a speedy work with the device, it is advantageous if the tensioning belt is inserted in the first position, before inserting the logs in the space between the side walls of both trestles so that it rests centrally on the pallet and each over the upper connecting webs of the support blocks is laid and at the same time extends transversely across the belt deflection. He is over a turnbuckle lockable and tensioned. The one end of the strap is connected to the turnbuckle self-locking. Of course, two straps can be inserted, which are then preferably insert each near the side walls.
Weiterhin kann das erfindungsgemäße Spannschloß zwei zueinander parallele Seiten- oder Gehäuseplatten (-bleche) besitzen, zwischen denen einerseits eine Einsteck- oder Blockiereinrichtung vorhanden ist. Diese besteht aus drei Rundbolzen die in Gurtbreite-Abstand in Dreieck-Formation so befestigt sind, daß vorzugsweise zwei Bolzen quer achssymmetrisch zueinander angeordnet sind, während der dritte Bolzen zu diesen mittig versetzt ist, so daß der Gurt um diese Bolzen selbsthemmend festgeschlungen blockierbar ist. Andererseits ist am Spannschloß eine Aufwickeleinrichtung vorhanden, bestehend aus einem sich zwischen den Seitenplatten senkrecht quer erstreckenden und rotierbaren längsdiagonal geschlitzten Aufnahmerohr. Dieses ist einerseits an der einen Platte drehbar befestigt und andererseits mit einer außerhalb der einen Seitenplatte angeordneten Ratschenzahnrad verbunden, das wiederum mit einem Zahnhebel oder Schnäpper zusammenwirkt. Dabei ist am Aufnahmerohr an beiden Enden mittig je eine Vierkantöffnung vorgesehen, als Stecköffnung für einen Betätigungshebel, vorzugsweise einen üblichen Ratschenschlüssel. Das Spannschloß ist somit in einfacher Weise so ausgelegt, daß ein Gurt einfach und sicher mit seinem einen Ende festgeschlungen werden kann, während das andere Ende einfach in den Aufnahmeschlitz eingesteckt und über ein handelsübliches Ratschenwerkzeug (Knarre) effizient spannbar ist. Für die universelle Nutzung des Spannschlosses können somit Gurte mit beliebiger Länge als Meterware ohne Hilfsmittel verwendet oder ausgetauscht werden.Furthermore, the turnbuckle invention may have two mutually parallel side or housing plates (sheets), between which on the one hand a plug-in or blocking device is present. This consists of three round bolts which are fastened in belt width distance in triangular formation so that preferably two bolts are arranged transversely symmetrical to each other, while the third bolt is offset centrally to these, so that the belt is self-locking locked locked these bolts. On the other hand, a take-up device is present on the turnbuckle, consisting of a vertically extending transversely between the side plates and rotatable longitudinally slotted receiving tube. This is on the one hand rotatably mounted on the one plate and on the other hand connected to an outside of a side plate arranged ratchet gear, which in turn cooperates with a toothed lever or latch. In this case, a square opening is provided centrally on the receiving tube at both ends, as a plug-in opening for an actuating lever, preferably a conventional ratchet wrench. The turnbuckle is thus designed in a simple manner so that a belt can be easily and securely fastened with its one end, while the other end is simply plugged into the receiving slot and over a standard ratchet tool (ratchet) is efficiently tensioned. For the universal use of the turnbuckle straps of any length can be used as meter goods without aids or replaced.
Schließlich ist von großem Vorteil, wenn der Vorrichtung auch ein selbstspannender Gurtgreifer zugeordnet ist, der im Einsatz über einen an seiner Halterung unterseitig vorgesehenen Einsteckbolzen den Spanngurt der fertiggestellten Bunde untergreift, so daß diese sicher angehoben und transportiert werden können. Dafür sind an der Halterung zwei zweiarmige fragezeichenförmige Hebel schwenkbar so befestigt, daß beim Anheben der Bunde, entsprechend dem Bundgewicht, die unteren geradlinigen Hebelarmen nach unten auf dem Gurt aufstehend zueinander verschwenkt werden, gleichzeitig über den Einsteckbolzen den Gurt nach oben zwischen die Hebelarme ziehend.
Günstig ist, wenn achsmittig in der aus zwei parallelen Seitenplatten bestehenden Halterung des Gurtgreifers ein ebenfalls aus zwei Platten zusammengesetzter Mitnehmer vorgesehen ist, der einerseits am oberen Ende einen Halte-Bolzen für die Hebezeuge und am anderen unteren Ende einen Mitnehmer-Bolzen besitzt. Dieser ist in axialen Führungsschlitzen der Halterungsplatten geführt und verschiebt bzw. drückt dabei gleichzeitig die oberen geschweiften Hebelarme auseinander. Dadurch werden die unteren Hebelarme zueinander verschwenkt und in maximaler Spannungsstellung ca. parallel zueinander ausgerichtet. Somit wird durch das Nachspannen durch den Gurtgreifer während des anhebenden Transportes der Bunde jeweils die freiwerdende Gurtlänge von der Halterung zwischen den sich auf dem Gurt aufstützenden Hebelarmen hochgezogen.Finally, it is of great advantage if the device is also associated with a self-tensioning belt gripper, which engages in use on a lower side provided on its mounting bolts the strap of the finished collars so that they can be safely lifted and transported. For this purpose, two two-armed question mark shaped lever are pivotally mounted on the bracket so that when raising the bundles, according to the federal weight, the lower rectilinear lever arms are pivoted down on the belt to each other, simultaneously pulling the belt over the pin up between the lever arms.
It is favorable if, in the center of the support consisting of two parallel side plates of the belt gripper, a driver likewise composed of two plates is provided, which on the one hand has a retaining bolt for the lifting gear at the upper end and a driving bolt at the other lower end. This is guided in axial guide slots of the support plates and displaces or pushes while the upper curly lever arms apart. As a result, the lower lever arms are pivoted to each other and aligned approximately parallel to each other in the maximum voltage position. Thus, by the retightening by the Gurtgreifer during the lifting transport of the bundles in each case the released belt length is pulled up by the holder between the lever arms supporting on the belt.
Die Aufgabe wird auch durch ein System zum Herstellen und Transportieren von Bunden aus Stapelgut, z. B. von Bunden aus Holzscheiten, dadurch gelöst, daß dieses besteht aus:
- mindestens einer Vorrichtung gemäß Ansprüchen 1 - 9, in Kombination mit mindestens gleich vielen Europaletten,
- mindestens einem Spanngurt mit einem Spannschloß mit den
Merkmalen gemäß Anspruch 8, und - bedarfsweise einem selbstspannenden Gurtgreifer mit den
Merkmalen gemäß Anspruch 9.
- at least one device according to claims 1-9, in combination with at least the same number of europallets,
- at least one strap with a turnbuckle with the features of
claim 8, and - If necessary, a self-tensioning belt gripper with the features according to
claim 9.
Von Vorteil ist vor allem, wenn das System zusammengesetzt ist aus:
- mindestens einer Europalette, vorzugsweise aus zwei und mehr Paletten,
- einem auf der/den Europalette/n unverschiebbar, aber abnehmbar aufsetztbaren Stützbock,
- einem auf der/den Europalette/n verschiebbar und abnehmbar aufsetzbaren Stützbock, mit daran befindlichem Stützkeil, Arretierungshebel und Fußhebel,
- mehreren Spanngurten, denen je ein Spannschloß zugeordnet ist,
- und bedarfsweise mindestens einem selbstspannenden Gurtgreifer, der an einem Hebezeug über seinen oberen Haltebolzen anbringbar ist und dabei mit seinem unteren Einsteck-Bolzen den Gurt untergreift und entsprechend spannt.
- at least one europallet, preferably two or more pallets,
- a supporting block fixed on the Euro pallet (s), but non-displaceable but detachable
- a supporting block which can be slidably and removably mounted on the Euro pallet (s), with supporting wedge, locking lever and foot lever attached thereto,
- several straps, each associated with a turnbuckle,
- and, if necessary, at least one self-tensioning belt gripper, which is attachable to a hoist via its upper retaining bolt and engages below the belt with its lower plug-in bolt and tensioned accordingly.
Schließlich wird die Aufgabe durch ein Verfahren zum Herstellen und Transportieren von Bunden aus Stapelgut, z. B. von Bunden aus Holzscheiten, unter Verwendung einer Vorrichtung nach den Ansprüchen 1 - 9, und/oder eines Systems nach den Ansprüchen 10 und 11 dadurch gelöst, daß eine Europalette auf eine Unterlage wie Boden o.ä. gelegt/gestellt wird. Darauf werden nacheinander die beiden Stützböcke auf die Europalette aufgesteckt, wonach ein Spanngurt zwischen die Seitenwände der Stützböcke, in Längsrichtung der Palette mittig so eingelegt wird, daß er in der Mittelzone der Einlege- Ausnehmung am Boden der Palette aufliegt und an den Stützböcken über deren obere Verbindungsstege nach außen führend gehängt ist. Dabei ist er gleichzeitig über den Stab der Gurtumlenkung des verschiebbaren Stützbockes geführt, wobei auch ein Spannschloß mit den das Spannschloß betreffenden Merkmalen des Anspruchs 8 griffbereit gelegt oder an einem der Gurtenden bereits befestigt ist.
Danach werden die Holzscheite in die Einlege-Aufnahmen zwischen die Stützböcke eingelegt, bis die entsprechende runde Bundform erreicht ist, wonach das lose Enden des Spanngurtes hochgehoben und um den aufgeschichteten Bund gelegt wird, während das andere Gurtende in den Schlitz des Aufwickelrohres so eingesteckt und eingezogen wird, so daß der Gurt eine erste Umschlingungsspannung erhält.
Dann wird mittels eines Ratschenschlüssels das Aufwickelrohr gedreht, selbsthemmend durch Zahnrad und Schnepper gehalten, wodurch der Gurt aufgewickelt und die Gurtspannung entsprechend erhöht wird, wodurch der Gurt auf die radial in das Bundinnere sich erstreckende Gurtumlenkung eine radiale Verschiebkraft ausübt. Sodann wird am verschiebbaren Stützbock der Verriegelungshebel gelöst, wodurch entsprechend der Gurtspannung der Stützbock verschoben wird, wobei kontinuierlich weitergespannt wird, bis die Gurtumlenkung komplett aus dem Bundinneren gedrückt ist. Schließlich wird das Bund seinem Zweck zugeführt, d. h. zur Einlagerung oder zu einer Sägeeinrichtung verbracht, wobei ein Gurtgreifer mit dem den Gurtgreifer betreffenden Anspruch 9 zum Einsatz kommt und das Bund am Gurt ergreifend weghebt, oder es werden die beiden Stützböcke von der Palette abgehoben und das Bund auf der leeren Palette verbleibend abtransportiert.Finally, the object is achieved by a method for producing and transporting bundles of staple goods, for. B. of logs from logs, using a device according to claims 1-9, and / or a system according to
Thereafter, the logs are inserted into the insert receptacles between the support brackets until the corresponding round collar shape is reached, after which the loose ends of the tension belt is lifted and placed around the stacked waistband, while the other end of the belt inserted into the slot of the takeup tube and retracted so that the belt receives a first loop tension.
Then, the take-up tube is rotated by means of a ratchet wrench, held self-locking by gear and Schnepper, whereby the belt is wound and the belt tension is increased accordingly, whereby the belt exerts on the radially in the collar extending belt deflection a radial displacement force. Then, the locking lever is released on the sliding support block, whereby according to the belt tension of the support bracket is moved, being continuously further tensioned until the belt deflection is completely pushed out of the collar inside. Finally, the federal government is its purpose fed, ie spent for storage or to a sawing device, with a belt gripper with the
Von Vorteil ist, wenn zum Verschieben des Stützbockes mit der gewünschten Gurtkraft, jeweils zumindest kurz der Fußhebel betätigt wird, der dabei kippt und auf den ihn durchdringenden Steg eine Gegenkraft ausübt und damit die Reibung zwischen Steg und den Deckbrettern der Palette verringert.It is advantageous if for moving the support bracket with the desired belt force, respectively at least briefly the pedal is operated, which tilts and exerts a counter force on the web penetrating it and thus reduces the friction between the web and the cover boards of the range.
Nach erfolgter optimaler Gurtspannung über das Spannschloß und ausreichendem Längsverschieben des Stützbockes kann nun das Bund nach oben über einen selbstspannenden Gurtgreifer, vorzugsweise den Gurtgreifer mit den Merkmalen des Anspruchs 9, ausgehoben und einem weiteren Vorgehen, Zersägen oder Lagern, zugeführt werden.
Es kann aber auch nach erfolgter optimaler Gurtspannung über das Spannschloß und ausreichendem Längsverschieben des Stützbockes das Bund auf der Palette verbleiben. Die beiden Stützböcke werden dabei von der Palette abgehoben und einer eventuellen entsprechenden Wieder- oder Weiterverwendung im Zusammenhang mit einer leeren Europalette zugeführt, während die Palette mit darauf gegen Wegrollen z. B. über Keile abgestütztem Bund, z. B. mithilfe eines Gabelstaplers abtransportiert wird.After the optimal belt tension on the turnbuckle and sufficient longitudinal displacement of the support bracket, the collar can now be lifted above a self-tensioning belt gripper, preferably the belt gripper with the features of
But it can also remain after the optimal belt tension on the turnbuckle and sufficient longitudinal displacement of the support bracket, the federal government on the pallet. The two trestles are lifted from the pallet and a possible corresponding re-use or re-use in connection with an empty Euro pallet, while the pallet with it against rolling z. B. via wedges supported collar, z. B. is transported by means of a forklift.
Zusammenfassend wird nochmals darauf hingewiesen, daß durch die erfindungsgemäße Vorrichtung die Spannkraft des Gurtes in das Zentrum des Bundes umgeleitet und dadurch eine zentrale Verdichtung erreicht wird. Die beim Spannen des Spanngurtes auf den Stützbock wirkende Kraft wird gleichzeitig zum Lösen des Bundes aus den Stützböcken, die zur Formung des Bundes notwendig sind, genutzt.In summary, it should again be noted that redirected by the inventive device, the clamping force of the belt in the center of the Federal and thereby a central compression is achieved. The force acting on the trestle during tensioning of the tension belt is simultaneously utilized for releasing the collar from the trestles which are necessary for forming the collar.

Es ist zu erkennen, daß hier als Grundplatte eine Europalette1 zum Einsatz kommt, die in bekannter Weise aus fünf sich zueinander parallele längserstreckenden Deckbrettern16 besteht, mit Zwischenräumen 17 dazwischen. Darunter sind drei Querbretter 18 vorhanden, eines jeweils an den äußeren Enden und eines mittig. Unter den Querbrettern 18 sind jeweils drei Distanzstücke 19 vorhanden, unter denen wiederum drei Kufen 20 angebracht sind, die sich in Längsrichtung der Palette erstrecken.
Die beiden Seitenwände 4, 5 der Stützböcke 2, 3 besitzen unterseitig innen jeweils eine innere Stufung 22, wodurch eine innere Abstützschulter 23 zum Abstützen auf dem inneren Querbrett 18 vorhanden ist. Zudem besitzen die Seitenwände des unverschiebbaren Stützbockes eine äußere Stufung 24, wodurch eine Abstützschulter 25 gebildet ist. Zwischen den beiden Stufungen oder Abstützschultern ist eine Längsleiste 26 vorhanden, die sich im Zwischenrum zwischen den beiden Querbrettern erstreckt und zum Steckverbinden des Stützbockes mit der Palette dient. Bei den Seitenwänden des verschiebbaren Stützbockes 3 ist keine äußere Stufung vorgesehen, bzw. diese ist so weit nach innen erweitert, in einer Schräge 27 zur inneren Stufung führend, daß der Stützbock 3 ungehindert um etwas mehr als die Eindringtiefe der Gurtumlenkung verschoben und dann ungehindert (stufenlos) entnommen werden kann.In

Die beiden Seitenwände 4, 5 des linken, unverschiebbaren Stützbockes 2 sind über mehrere Verbindungsstege 29 fest miteinander verbunden. Auch beim verschiebbaren Stützbock 3 sind ähnliche Verbindungsstege vorhanden, wobei hier die unteren beiden Stege 30, 31 eine genau vorbestimmte Lage und Funktion besitzen. Der dem Bund 6 abgewandte, äußere Steg des Stützbockes 3 ist so angebracht, daß er und damit der äußere Teil des Stützbockes 3 auf der Palette 1vertikal abgestützt ist. Dieser Steg 30 ist quer durch einen Fußhebel 32 geführt, der eine Öffnung 33 besitzt, die eine gegenseitige Verschiebe- und Kippbewegung zuläßt, wobei über den Fußhebel eine Hebelkraft auf den Stützbock ausgeübt werden kann.

Der innere Verbindungssteg 31 ist so angeordnet, daß er nicht auf der Palette aufliegt. Er durchsetzt dabei einen an ihm über eine dreieckige Öffnung 37 kippbar angeordneten Verriegelungshebel 36, der aus zwei parallelen Wänden 38 besteht, die unterseitig je eine hakenförmige Stufung 39 besitzen. Diese Stufungen 39 greifen in eingerückter (erster) Beladungsstellung des Stützbockes in die inneren Zwischenräume 17 so ein, daß sie an der Innenseite des äußeren Querbrettes anstehen, wodurch eine einfache Sicherung gegen Verschieben auf der Palette vorhanden ist. Auf diesem Verbindungssteg 31 ist zudem mittig zum Stützbockes der Stützkeil 11 angeordnet, durch den der Steg über ein Langloch 40 verschieblich hindurchgeführt ist. Dabei ist das Langloch so ausgelegt, daß der Steg in der verriegelten Position des Stützbockes 3 während des Stapelns auch den Stützkeil 11 stützt. Schließlich ist aus den

Die drei Rundbolzen 45 sind dabei in Dreieck-Formation so angeordnet, daß zwei Bolzen quer achssymmetrisch zueinander angeordnet sind, während der dritte Bolzen achsmittig versetzt ist, so daß der Gurt um diese leicht schling-blockierbar ist. Zudem ist am Spannschloß eine Aufwickeleinrichtung 47 vorhanden, bestehend aus einem sich zwischen den Seitenplatten 44 quer erstreckenden und rotierbaren längsdiagonal mit einem Schlitz 49 versehenen Aufnahmerohr 48, das einerseits über einen Kopf 52 an der einen Seitenplatte 44 verdrehbar abgestützt ist und andererseits mit einer außerhalb der anderen Seitenplatte 44 angeordneten RatschenZahnrad 50 fest verbunden ist. Das Zahnrad 50 wirkt mit einem Zahnhebel oder Schnäpper 51 zusammen, der auf einem nach außen abragenden Ende eines der Rundbolzen 45 verschwenkbar aufsitzt. An beiden Enden des Aufnahmerohres bzw. an dessen Kopf oder Zahnrad, Ist zentral/mittig je eine Vierkantöffnung 53 vorgesehen ist, als Stecköffnung für einen Betätigungshebel, vorzugsweise einen Ratschenschlüssel oder Knarre 54. Der Schnäpper greift dabei mit seinen Zähnen 55 in das Zahnrad 50 ein. Zum Öffnen des Spannschlosses oder Lockern des Spanngurtes ist lediglich an einem exzentrischen Lösezapfen 56 an der Unterseite des Schnäppers zu drücken, wodurch dieser nach außen kippt und aus der Verzahnung mit dem Zahnrad gelöst wird.
Das Spannschloss wird somit selbsthemmend mit dem Spanngurt verbunden. Um die maximale Übertragung der Zugkraft des Spanngurtes auf das Spannschloss durch Selbsthemmung zu erreichen, muss das eine Ende des Gurtes 13 entsprechend dem in

Die erfindungsgemäße Vorrichtung oder das erfindungsgemäße System arbeitet folgendermaßen (Verfahren):
- Auf eine am
Boden aufliegende Europalette 1 wird zuerst der unverschiebbare Stützbock 2 so aufgesteckt, daß er mitden unteren Längsleisten 26 4, 5 inseiner Seitenwände die äußeren Zwischenräume 17 der Palette eingreift, wobei die Einlege-Ausnehmungen 7 zur Palettenmitte weisen. Danach wird in ähnlicher Weise, jedoch spiegelbildlich zum Stützbock 2, der verschiebbare Stützbock 3 auf die Palette gesetzt, wobei der an diesem befindliche Verriegelungshebel 36 nach unten gedrückt wird, so daß er mit seinen hakenförmigen Stufungen 39 inden inneren Zwischenräumen 17 an der Innenseite des äußeren Querbrettes 18 klemmend ansteht. Danach wird der Stützkeil 11 nach außen verschoben, bis ermit seinem Langloch 40am Verbindungssteg 31 ansteht. Schließlich wird der Fußhebel 32 nach außen geschoben, bis ermit seiner Öffnung 33am Verbindungssteg 30 ansteht. Dann wirdein Spanngurt 13 entsprechender Länge genommen und an dessen einemEnde das Spannschloß 14 bereits vorhergehend über diedrei Rundbolzen 45 klemmend eingeschlungen befestigt wurde.Dieser Spanngurt 13 wird nun quer mittig in Längsrichtung der Palette so eingelegt oder eingehängt, daß er zwischen 4, 5 der beiden Stützböcke 2, 3 mittig auf der Oberfläche der Palette aufliegt, während er nach außen über die oberen Verbindungsstege 19 der Stützböcke geführt, jeweils außen nach unten hängt. Dabei liegt er auch anden Seitenwänden der Stange 9 der radial-horizontal nach innen ragenden Gurtumlenkung 8 tangential an.
- On a lying on the
ground Euro pallet 1, theimmovable support bracket 2 is first fitted so that it engages with the lowerlongitudinal strips 26 of its 4, 5 in theside walls outer spaces 17 of the pallet, the insertion recesses 7 point to the center of the pallet. Thereafter, in a similar manner, but in mirror image to thesupport frame 2, the slidingsupport bracket 3 is placed on the pallet, wherein the lockinglever 36 located thereon is pressed down so that it with its hook-shapedsteps 39 in theinner spaces 17 on the inside of theouter cross-board 18 is clamped. Thereafter, thesupport wedge 11 is displaced outwards until it is present with itsslot 40 on the connectingweb 31. Finally, thefoot lever 32 is pushed to the outside until it is present with itsopening 33 on the connectingweb 30. Then, atension belt 13 is taken corresponding length and at one end of theturnbuckle 14 has already been clamped previously clamped over the threeround bolts 45. Thistension belt 13 is now inserted or suspended transversely in the middle in the longitudinal direction of the pallet so that it rests centrally between the 4, 5 of the twoside walls 2, 3 on the surface of the pallet while being guided outwardly over the upper connectingsupport brackets webs 19 of the support brackets , each outside hanging down. He is also on therod 9 of the radially-horizontally inwardly projectingbelt deflection 8 tangentially.
Danach kann mit dem Einschichten der Holzscheite begonnen werden. Wenn die Einschichtung beendet ist, also das Bund 6 die durch die Ausnehmungen 7 vorbestimmte runde Form erhalten hat, wird der Spanngurt 13 um das Bund so gelegt, daß das eine Ende mit dem Spannschloß 14 sich ungefähr im oberen Scheitelpunkt des Bundes befindet. Dann wird das andere Gurtende in den Schlitz 49 des Aufnahmerohres 48 der Aufwickeleinrichtung 47 des Spannschlosses gesteckt, eingezogen und über einen Steckschlüssel, vorzugsweise einen üblichen Ratschenschlüssel (eine Knarre) das Aufnahmerohr gedreht und dadurch der Gurt um das Bund gespannt.Then you can start with the layering of the logs. When the stratification is completed, so the
Zu Beginn des Spannvorganges übt das lose zwischen den Stützböcken 2, 3 aufgeschichtete Scheitholz Auflagekräfte auf die Stützböcke und den Stützkeil 11 aus. Diese Auflagekräfte werden in den Auflagepunkten "A" (Kraft KA am inneren Querbrett) und "B" (Kraft KB am äußeren Querbrett) des verschiebbaren Stützbockes 3 sowie über den Keil 11 (Kraft KK) auf die Palette übertragen (siehe in
Dann wird der Verriegelungshebel 36 gelöst und der Gurt 13 weiter gespannt. Durch die Zunahme der Spannkraft des Gurtes wird die auf den Stützbock über die Gurtumlenkung 8 horizontal wirkende Gurtkraft (KG) erhöht. Da die zwischen dem Stützbock und der Palette wirkenden Reibungskräfte größer sind als die horizontal auf die Gurtumlenkung wirkende Kraft, wird über den äußeren Auflagepunkt "B" eine Hebelwirkung ausgeübt. Die so erzeugte Hebelkraft ist erheblich kleiner als die auf den Stützbock wirkende Auflagekraft des Bundes. Die auf die Gurtumlenkung wirkende Gurtkraft erhöht so die Auflagekraft KB im Punkt "B" und erhöht damit die zwischen dem Stützbock 3 und der Palette wirkende Reibungskraft. Es stellt sich ein Kräftegleichgewicht zwischen der horizontalen Gurtkraft KG, die auf den Stützbock wirkende Auflagekraft des Bundes und den Reibungskräften zwischen dem Stützbock und der Palette ein.Then, the locking
Der Stützbock löst sich erst dann aus dem Formschluß mit dem Bund, wenn die in den Auflagepunkten "A" und "B" wirkenden Reibungskräfte kleiner sind als die horizontal wirkende Gurtkraft (KG). Durch Betätigung des Fußhebels 3 2 kann die Auflagekraft (KA) im Auflagepunkt "B" entlastet werden. Dadurch verlagert sich ein Teil der Reibung zwischen dem Steg 30 des Stützbockes und der Palette auf die Gleitfläche zwischen dem metallischen Fußhebel 32 und dem metallischen Steg 30 des Stützbockes 3. Wegen des geringeren Reibungskoeffizienten der metallischen Reibung verringert sich die auf den Stützbock wirkende gesamte Reibungskraft. Wenn die Reibungskräfte auf diese Weise geringer werden als die horizontal wirkende Gurtkraft, wird der Stützbock aus dem Formschluß mit dem Bund ausgerückt. Auf diese Weise kann die für den Spannvorgang gewünschte Gurtkraft durch die über den Fußhebel wirkende Entlastungskraft beeinflußt werden.The trestle only releases from the positive engagement with the collar when the frictional forces acting in the support points "A" and "B" are smaller than the horizontally acting belt force (KG). By pressing the
Nachdem der Gurt die Gurtumlenkung etwa bis zur Hälfte seiner Länge aus dem Bundquerschnitt gedrückt hat, stößt der vordere Steg 31 gegen die gegenüberliegende Seite des Langloches im Keil und löst nun auch den Keil aus seinem Formschluß mit dem Bund. Erst wenn die Gurtumlenkung vollständig aus dem Bundquerschnitt gedrückt ist, können beide Stützböcke von der Palette genommen werden.After the belt has pushed the belt deflection about half its length from the collar cross-section, the
Mit der erfindungsgemäßen Vorrichtung können Bunde mit einem Inhalt von einem Raummeter hängend in die gewünschte Scheitlänge gesägt werden. Dazu wird das, wie oben beschrieben, verdichtete Bund mittels eines selbstspannenden Gurtgreifers am Gurt von der Palette oder aus dem Stapel genommen. Die beim radialen Durchsägen des Bundes auftretende Auflockerung des Querschnitts wird mittels des selbstspannenden Gurtgreifers nachgespannt. Das Bund kann im Bereich der Hubhöhe z.B. eines Gabelstaplers gesägt werden. Die abgesägten Scheite können auf eine Rutsche fallen und zu einem Förderband oder in eine Box mit dem Inhalt eines oder mehrerer Schüttmeter geleitet werden.With the device according to the invention bundles can be sawed with a content of one room meter hanging in the desired log length. For this purpose, as described above, compacted collar is taken by means of a self-tensioning belt gripper on the belt from the pallet or from the stack. The loosening of the cross section occurring during radial sawing of the collar is re-tensioned by means of the self-tensioning belt gripper. The federal government can in the range of lifting height, e.g. sawing a forklift. The sawed logs can be dropped onto a chute and sent to a conveyor or box containing the contents of one or more meters of bulk material.
Es kann aber auch das Bund auf der Palette verbleiben und zusammen mit dieser abtransportiert werden, wobei vorhergehend die beiden Stützböcke von der Palette abgehoben und das Bund über untergeschobene Keile (oder Holzscheite) gegen Wegrollen gesichert werden.But it can also remain the federal government on the pallet and be transported along with this, with previously lifted the two trestles from the pallet and the federal government on deferred wedges (or logs) are secured against rolling away.
Die beiden abgehobenen Stützböcke können nun auf eine andere, bereitgestellt Palette aufgesteckt werden, ein anderer Spanngurt 13 mit Spannschloß 14 eingelegt und in gleicher Weise mit dem Herstellen eines neuen Bundes weiter verfahren werden.

- Method for manufacturing, transporting and sawing bundles from stacked goods, e. g. log bundles, using a device according to Claims 1-9 and/or a system according to Claims 10 and 11, by means of the following steps:- a euro-pallet (1) is placed on a foundation, such as a floor or the like;- then the two trestles (2, 3) are successively plugged onto the euro-pallet;- after this, a tension belt (13) is inserted between the lateral walls (4, 5) of the trestles in the longitudinal direction of the pallet such that it rests on the bottom of the pallet in the central zone of the insertion recess and is placed on top of the upper connecting racks (19) of the trestles, while at the same time being guided over the bar (9) of the belt reversing mechanism (8) of the slidable trestle (3), a turnbuckle (14) with the features concerning the turnbuckle of Claim 8 also being connected to the belt;- after this, the logs are placed in the insertion recesses (7) until the respective round bundle shape is achieved;- then the loose end of the belt is lifted and laid over the stacked bundle (6) and inserted and pulled into the slot (49) of the receiving tube (48) of the turnbuckle (14) fastened in a self-locking manner to the other end of the belt, such that the tension belt is subjected to a first winding tension;- after this, the receiving tube (48) of the turnbuckle (14) is turned by means of a ratchet wrench (54), with the tension belt being wound up and the belt tension being increased accordingly, the tension belt (13) exerting a radial sliding force on the belt reversing mechanism (8) extending radially into the interior of the bundle;- then the locking lever (36) on the slidable trestle (3) is released with the trestle (3) being shifted outward depending on the belt tension, further tightening taking place continuously with actuation of the foot lever until the belt reversing mechanism (8) has been completely pressed out of the interior of the bundle;- the bundle (6) is then finally transported to its destination, that is, to a storage place or to a sawing unit, a belt gripper (58) with the features concerning the belt gripper according to Claims 11 and 12 being used, lifting the bundle (6) by the tension belt and moving it away; or the two trestles (2, 3) being lifted from the pallet and the bundle remaining on the empty pallet being transported away.
- Method according to Claim 12, characterized in that for continuous sliding of the trestle (3) under the desired tension of the tension belt (13) the foot lever (32) is actuated at least briefly for setting the belt tension, with the lever tilting and reducing the load pressure of the rack (30) penetrating through it on the cover boards of the pallet, thus reducing friction between the pallet and the trestle.
- Method according to Claim 12, characterized in that after the belt tension has been set optimally over the turnbuckle (14) and the trestle (3) has been sufficiently displaced in the longitudinal direction, the bundle (6) is lifted up over the self-tightening belt gripper (58).
- Method according to Claim 12, characterized in that after the belt tension has been set optimally over the turnbuckle (14) and the trestle (3) has been sufficiently displaced longitudinally, the bundle (6) remains on the pallet (1) while the trestles (2, 3) are lifted from the pallet and forwarded to a possible re-processing or further processing in connection with an empty euro-pallet, the pallet being transported away, for example by a fork lifter or lift truck, with the bundle on it secured against rolling, for instance by means of wedges.
